Before looking at the results, note that there was nothing particularly clever about the selection of stocks (the 12 largest stocks in the U.S. by market capitalization at the time the first article was written) or the timing (I suggested selling calls after a significant increase in the market and selling puts after a significant decrease). The following chart shows that I was not nailing any tops or bottoms.
Half of the stocks would neither be put nor called, leaving the investor in the same position as in a passive strategy, except for the joy of pocketing the option premiums. The shares that exceeded the call strike prices at expiration and therefore being sold were WMT, AAPL, GOOG, IBM, and PG. Only BAC shares ended lower than the put strike price and would therefore leave the investor with a double dose of that troubled bank. The portfolio can obviously be rebalanced at any time.
